If you're using functional hardware, you'll need to measure for the hinge offset. For easier measuring, place a flat piece of wood along the wall, extending beyond the window frame.

For Window Frame-Mount Hinges:

Measure from the window frame to the back of the wood. This dimension is considered your offset and is used when selecting hinge offset.

For Jamb-Mount Hinges:

Measure from the back of the window frame jamb to the back of the wood, and then add the thickness of the shutter. This dimension will tell you how many "inches open" you need when ordering leaf-style hinges, such as our "H" Style Lift Off Hinges or Lull & Porter Hinges.

Note the window frame width.

Also note the wall's texture. Is it covered with brick, stone or siding?
